To say Brawl is a warrior is like calling Cybertron a hunk of metal. Brawl does not just enjoy fighting, he's consumed by it. Tearing Autobots apart is embedded into his very core, and every fiber-optic cable of his being is obsessed with wild, unyielding combat. The only thing he enjoys, or even cares about, is the fury of battle. And he loves a good explosion. Particularly if it's one he created, and if it's an Autobot that's exploding.

While it's not uncommon for ambition or independent thinking to cause trouble in the Decepticon ranks, Brawl's never had that problem. This is mostly because he suffers from a severe lack of both qualities. Where others question orders, Brawl simply carries them out, perfectly happy to let Megatron do all his thinking for him.
